How can we improve the OneDrive experience on Windows?

Ability to download a folder on the Windows Phone app

I use Onedrive for many things, including for hosting my music on the cloud. It allows me to quickly download some music on my phone from the cloud. Today I realised that it is not possible to download a folder from the WP app, only files. So in my example, I had to open the folder (an album), to select all the songs in it, then to download it.

Not a big deal, but it made me realize it would be an easy improvement to allow the user to download the folder directly.

OneDrive is my productivity tool across all devices, including Windows 10 phone.

Microsoft,
are you going to "KILL" your mobile phones completely?
Put yourself into the shoes of a business person who seeks efficiency and user-friendly devices.
I start regretting to have switched to the most expensive Windows 10 phone on the market, when only realizing in hindsight, that FULL SYNCHRONIZATION with ONEDRIVE is not doable, not even entire FOLDERS, and in addition, ".MSG" files cannot be opened / viewed on a Windows 10 Phone.

Please get your act together and accomplish your promisses made long ago.

Over a year since last update. @Douglas Pearce, can you give us any updates on the status of this? Would love to see this functionality. It is nice to be able to set individual files to be available offline, but doing this at the folder level would be great!
